In an interview with Gaming Bolt, creative director Brian Hayes confirmed that EA Sports UFC will be rendered at 1080p. However, it will only run at 30 frames per second with motion blur, something he explained in the interview.
"UFC is running at 1080p. The game sim is running at 60 FPS, but rendering at 30 FPS with motion blur. From prior experience working on Fight Night Round 4 and Fight Night Champion, which rendered at 60 and 30 FPS respectively, we discovered that 60 FPS didn't have a hugely beneficial impact on gameplay, but motion blur had an enormous impact on visual quality. In fact, when we focus tested the two, the majority of people preferred the 30FPS experience with motion blur. So, as opposed to arbitrarily jumping back to 60 FPS for little discernible benefit, we decided to put those resources towards improving the visual presentation of the game in other ways."
